Abstract (en)
[origin: EP2612995A2] The present application provides a compartmentalized cooling system (100) for providing a cooling flow (170) in a turbine (40) with a flow of combustion gases (35) therein. The compartmentalized cooling system (100) may include a turbine nozzle (105) and a cooling baffle (200). The turbine nozzle (105) may include an airfoil insert (150) and a nozzle outer sidewall (140). The cooling baffle (200) may include a high pressure cooling passage (180) in communication with the airfoil insert (150) in a first circuit (300) and an impingement plate (230) positioned about the nozzle outer sidewall (140) in a second circuit (330).
